The Difference Between Deep Groove Ball Bearing And Angular Contact Ball Bearing

What is deep groove ball bearing

Deep groove ball bearing, formerly known as single-row centripetal ball bearing, is the most widely used rolling bearing. It is characterized by small friction resistance, high speed, can be used to bear radial load or radial and axial combined load at the same time on the machinery, can also be used to bear axial load on the machinery, such as small power motors, automobile and tractor gearboxes, machine tool gearboxes, general machinery, tools and so on.

Characteristics of deep groove ball bearing

Deep groove ball bearings are the most commonly used rolling bearings. Its structure is simple and easy to use. Mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has the performance of a certain angular contact ball bearing, and can bear radial and axial combined load. When the speed is high and the thrust ball bearing is not suitable, it can also be used to bear pure axial load. Compared with other types of bearings with the same specification and size as deep groove ball bearings, this kind of bearings has small friction coefficient and high limit speed. But not impact resistance, not suitable for heavy load.

Application of deep groove ball bearing

Deep groove ball bearings can be used in gearboxes, instruments and meters, motors, household appliances, internal combustion engines, traffic vehicles, agricultural machinery, construction machinery, engineering machinery, roller type roller skates, yo-yo, etc.

The difference between deep groove ball bearing and angular contact ball bearing

Different type and load direction:

Deep groove ball bearing: deep groove ball bearing is the most common type of rolling bearing. Mainly bear radial load, can also bear radial load and axial load. When it bears only radial load, the contact Angle is zero. When deep groove ball bearing has large radial clearance, it has the performance of angular contact bearing and can withstand large axial load. The friction coefficient of deep groove ball bearing is very small and the limit speed is also very high.

Angular contact ball bearing: the contact Angle between ring and ball, standard contact Angle is 15/25 and three kinds of 40 degrees, the greater the contact Angle, the greater the axial load capacity, the smaller the contact Angle is helpful for high-speed rotation, the single bearing can bear radial load and one-way axial load, the DB combination, combination of DF, and double row angular contact ball bearings can withstand radial load and axial load, two-way DT combination is suitable for large unidirectional axial load, the rated load of a single bearing is insufficient occasions, high speed ACH type bearings, ball diameter is small, the number of balls, mostly used in machine tool spindle. In general, angular contact ball bearings are suitable for high-speed and high-precision rotation occasions.

Structural differences:

Deep groove ball bearings with the same inner and outer diameter and width size and angular contact ball bearings have the same inner ring size and structure, while the outer ring size and structure are different:

1.deep groove ball bearing outer ring channel on both sides of the double shoulder, and angular contact ball bearing is generally single shoulder;

2. The raceway curvature of the outer ring of deep groove ball bearing is different from that of the angular contact ball, and the latter is often greater than the former;

3. The raceway position of the outer ring of the deep groove ball bearing is different from that of the angular contact ball bearing. The specific value of the non-central position is considered in the design of the angular contact ball bearing, which is related to the degree of the contact Angle.

In terms of use:

1.The two different purposes, deep groove ball bearing is suitable for small axial force and radial force, under, axial-radial joint load and torque load, and the single angular contact ball bearings can bear radial load, large axial load (vary with different contact Angle), twin pairs (varies with the pairing) can be subject to bi-directional load and torque load.

2.The limit speed is different, the limit speed of angular contact ball bearings of the same size is higher than that of deep groove ball bearings.
